| Research Abstract |
We studied and developed network control architecture to aim to establish a sustainable network system for power saving. We focused on following three sub-themes; (1) dynamic network re-configuration based on peak traffic estimation, (2) power saving with association control for wireless networks, (3) integrated control of wired and wireless networks for power saving. Especially, we proposed the traffic aggregation/distribution scheme that achieve a power saving and a load balancing in a whole network. Furthermore, to suppose the operation of actual networks, we evaluate the efficiency of the proposed scheme using traffic information flowing through the network of campus.
Finally, based on results of these sub-themes, we evaluated integrated network control architecture that each node in wired/wireless networks changes to active/sleep mode autonomously for power saving.
